Abstract

An image processing apparatus includes a hardware processor that: divides each of pixels of image data in units of blocks, and compresses the image data using a maximum value and a minimum value of a pixel value in each of the divided blocks; extracts a maximum value and a minimum value of each of the blocks from the compressed image data; detects an edge of an object on the basis of at least one of the extracted maximum value and the minimum value of each of the blocks; performs edge correction of the compressed image data by increasing or decreasing the maximum value and the minimum value of each of the blocks within a correction range from the detected edge; and decompresses the image data that have undergone edge correction, using the maximum value and the minimum value of each of the blocks.
